Although London was accustomed to heavy fogs, this one was denser and longer-lasting than any previous fog. Then, in 1952, a four-day fog dubbed The Great Smog hit amid a perfect storm of weather conditions, causing major disruption in transport. While better-quality "hard" coals (such as anthracite) tended to be exported to pay off World War II debts, post-war domestic coal tended to be of a relatively low-grade, sulphurous variety (similar to lignite) which increased the amount of sulphur dioxide in the smoke. The Big Smoke developed in London on Dec. 5, 1952, triggered by a period of cold weather collecting airborne pollutants, mainly from the coal fires that were used to heat homes at the time… The Big Smoke … Fog-penetrating fluorescent lamps did not become widely available until later in the 1950s. The casualties from the five day fog were unbelievable. Photo: TopFoto / The Image Works In December 1952, London experienced a catastrophe.

The Mystery Behind London’s “Killer Fog” of 1952 Has Finally Been Solved. [19], In the inner London suburbs and away from town centres, there was no disturbance by moving traffic to thin out the dense fog in the back streets. Een periode van koud weer, een hogedrukgebied en windstille omstandigheden zorgde ervoor dat luchtvervuiling, vooral afkomstig van de verbranding van steenkool in fabrieken en woningen, niet kon ontsnappen en als een dikke deken over de stad kwam te liggen. Een periode van koud weer, een hogedrukgebied en windstille omstandigheden zorgde ervoor dat luchtvervuiling, vooral afkomstig van de verbranding van steenkool in fabrieken en woningen, niet kon ontsnappen en als een dikke deken over de stad kwam te liggen. On the December 4 an anticyclone settled over the cold, windless London which caused a “temperature inversion” – where cold, stagnant air is trapped under a layer of warm air. It appeared to be just another winter day in the city. "Smog masks" were worn by those who were able to purchase them from chemists. Government medical reports in the weeks following the event estimated that up to 4,000 people had died as a direct result of the smog[1] and 100,000 more were made ill by the smog's effects on the human respiratory tract. Het duurde van 5 december tot 9 december, daarna verdween de ernstige luchtvervuiling snel nadat het weer was omgeslagen.

"A look back at the London smog of 1952 and the half-century since. [20] Most of the victims were very young or elderly, or had pre-existing respiratory problems. At the time, residents paid little attention to the strange event, writing it off as just another natural fog, but once it lifted, people started dying. [5], It caused major disruption by reducing visibility and even penetrating indoor areas, far more severely than previous smog events, called "pea-soupers". Despite improvements, insufficient progress had been made to prevent one further smog event approximately ten years later, in early December 1962. But over the next few days, conditions deteriorated, and … Dicas, Peters, Annette; Döring, Angela; Wichmann, H-Erich; Koenig, Wolfgang (1997) 'Increased plasma viscosity during an air pollution episode: a link to mortality?'. It persists for five days, leading to the deaths of at least 4,000 people. On December 4th 1952 the city of London found itself trapped underneath a wall of fog and by December 9th when the fog finally lifted, roughly 12,000 had died.

Eines davon war die Emission von schwefeldioxidhaltigem Rauch durch die weit verbreiteten Kohle-Heizungen. Diese Art des Smogs bezeichnet man als Wintersmog (Inversionswetterlage mit Schadstoffen im Kaltluftbereich). In December 1952, London was trapped in a deadly cloud of fog and pollution for five days — what became known as the Great Smog of 1952. When a thick fog swept over London in December of 1952, no one batted an eye.

[11], Research suggests that additional pollution-prevention systems fitted at Battersea may have worsened the air quality. Londoners were pretty used to fog, but as it began to roll in on 5 December 1952, this fog slowly began to show that it was something different and dangerous. Government-sponsored scientific research sought to dispense with the choking fog, to the annoyance of the statues. The Great Smog of London, or Great Smog of 1952, was a severe air pollution event that affected London, England, in December 1952. A period of unusually cold weather preceding and during the Great Smog led Londoners to burn much more coal than usual to keep themselves warm. An episode of The Goon Show entitled 'Forog', broadcast on the BBC Home Service 21 December 1954 was a thinly veiled satire on the killer fog crisis. Heavy smog begins to hover over London, England, on December 4, 1952. Among the dreary images which capture London's quintessentially British climate are several of the city's Great Smog of 1952, in addition to others which depict the clammy, summer fogs … [18] Outdoor sports events were also cancelled.

De Grote Smog van 1952 (Great Smog of '52) was een smogophoping die de Britse stad Londen teisterde in december 1952. [7][8] The Great Smog is thought to be the worst air pollution event in the history of the United Kingdom,[9] and the most significant for its effects on environmental research, government regulation, and public awareness of the relationship between air quality and health. [13], On 4 December 1952, an anticyclone settled over a windless London, causing a temperature inversion with cold, stagnant air trapped under a layer (or "lid") of warm air. Financial incentives were offered to householders to replace open coal fires with alternatives (such as installing gas fires), or for those who preferred, to burn coke instead which produces minimal smoke. [13] The absence of significant wind prevented its dispersal and allowed an unprecedented accumulation of pollutants. As depicted in the Netflix series The Crown (which last year aired on Chinese streaming sites) the disaster seemingly came out of nowhere, as sunny blue skies suddenly gave way to a choking, blinding, fog that enveloped the city and was more severe than anything many had seen before.

However, recent similar pollution-based fog over parts of the Eastern world, especially in China, have helped modern scientists pinpoint what the likely cause of London’s killer fog had been. [5] The relatively large size of the water droplets in London fog allowed the production of sulphates without the acidity of the liquid rising high enough to stop the reaction, and the resultant dilute acid become concentrated when the fog was burned away by the sun. At first, the weather phenomenon was hardly noticed, but as visibility got worse and worse until even the traffic in the city came to a standstill, some inhabitants of London started to get an uneasy feeling. A period of unusually cold weather preceding and during the Great Smog led Londoners to burn much more coal than usual to keep themselves warm. Fog, essentially a cloud at ground level, is influenced by nearby bodies of water, topography, wind, and weather conditions.

The most notorious incident — the “Great Smog” — occurred in December 1952. De gevolgen gaven de aanzet tot het doen van milieuonderzoek, overheidsregulatie en publiek besef met betrekking tot de relatie tussen luchtkwaliteit en gezondheid. This was made even worse at night since each back street lamp at the time was fitted with an incandescent light bulb, which gave no penetrating light onto the pavement for pedestrians to see their feet or even the lamp post.

On Friday 5 December 1952, a thick yellow smog brought the capital to a standstill for four days and is estimated to have killed more than 4,000 people. A new study appearing in Proceedings of the National Academy of Sciences suggests that there are indeed similar conditions that are conducive to dangerous or deadly fogs today.

[22] Most of the deaths were caused by respiratory tract infections, from hypoxia and as a result of mechanical obstruction of the air passages by pus arising from lung infections caused by the smog. However, recent similar pollution-based fog over parts of the Eastern world, especially in China, have helped modern scientists pinpoint what the likely cause of London’s killer fog had been. The fog was unable to escape and the presence of the tarry particles from the cheap sulphurous coal gave the smog an acrid smell and a yellow-black colour – hence the name pea-souper. [1][2], Environmental legislation since 1952, such as the City of London (Various Powers) Act 1954 and the Clean Air Acts of 1956 and 1968, led to a reduction in air pollution. A period of unusually cold weather, combined with an anticyclone and windless conditions, collected airborne pollutants—mostly arising from the use of coal—to form a thick layer of smog over the city. More recent research suggests that the total number of fatalities may have been considerably greater, with estimates of between 10,000 and 12,000 deaths.[1][2]. Bell ML, Davis D. 2001. Over 150,000 people were hospitalized for breathing related issues and the human death toll surpassed over … It is to be hoped that such an event will never recur-or be allowed to recur. Back in 1952 the coal being shovelled into furnaces in homes and factories across London released sulphur dioxide. A preliminary report, never finalised, blamed those deaths on an influenza epidemic. A fog so thick and polluted it left thousands dead wreaked havoc on London in 1952. It lasted from Friday 5 December to Tuesday 9 December 1952, then dispersed quickly when the weather changed. In December of 1952, the fog enveloped all of London and residents at first gave it little notice because it appeared to be no different from the familiar natural fogs that have swept over Great Britain for thousands of years. For five days in December 1952, a fog that contained pollutants enveloped all of London. A high pressure air mass settled over the Thames river and when the sun dropped, a cold front moved in from the west forcing any wind to come to a stop. Later onderzoek maakte aannemelijk dat dit waarschijnlijk een onderschatting was en schatte het werkelijke aantal doden door de smog op 12.000.
